KubeCon EU 2026 - From Hallucinations to Hardware: Diagnosing LLM Failures

I'm excited to share that I'll be co-presenting with my good friend Ryan Peirce at Cloud Native AI & Kubeflow Day! One of our favorite live demo sessions has been accepted and we'll both be in Amsterdam at KubeCon + CloudNativeCon Europe 2026.

In case you were still unaware, KubeCon + CloudNativeCon is the flagship conference of the Cloud Native Computing Foundation (CNCF), gathering adopters and technologists from leading open source and cloud native communities. The event brings together the entire cloud native ecosystem for education, collaboration, and networking opportunities.

Every year this event features multiple co-located events, and we're excited to be presenting at Cloud Native AI & Kubeflow Day, which focuses on the intersection of cloud native technologies and artificial intelligence workloads.

Below are all the details of our session at the time of this writing.

DevOpsCon Amsterdam 2026: It’s my docs, and I will cry if I want to!

My last DevOpsCon event was in Munich, so when I saw they were expanding and visiting my home country in Amsterdam, Netherlands I could not resist. I submitted a few things and the one that was selected is a talk I'm going to be testing based on my experiences over the last year as a maintainer on the Fluent Bit CNCF project.

I will be on-site at the Van der Valk Hotel Amsterdam-Amstel for DevOpsCon Amsterdam from 20-24 April 2026. They will have networking, sessions, and hands-on workshops available for all who attend.

Below you'll find my talk details and the schedule.

2025 Year in Review: Community, Contribution, and Changes

As we ease into the last few days of 2025, I like to close out this one last task: reflecting back on all the fun, challenges, and travel over the past year. While it takes a bit of research to gather all the facts and figures, it’s a rewarding effort. I’ve been sharing on this site for two decades now—no ads, no ulterior motives—just an honest effort to communicate with the world.

This year, the focus for me and my teams remained on the four pillars of our role: speaking, publishing, socializing, and hands-on content generation. 

While 2024 was about observability (o11y) taking center stage, 2025 was the year we put those theories into practice, accelerated our momentum, and stated to gain serious traction in the wild.

Mastering Fluent Bit: Developer Guide to Telemetry Pipeline Routing

This series is a general purpose getting started guide for those of us wanting to learn about the Cloud Native Computing Foundation (CNCF) project Fluent Bit.

Each article in this series addresses a single topic by providing insights into what the topic is, why we are interested in exploring that topic, where to get started with the topic, and how to get hands-on with learning about the topic as it relates to the Fluent Bit project.

The idea is that each article can stand on its own, but that they also lead down a path that slowly increases our abilities to implement solutions with Fluent Bit telemetry pipelines.

Let's take a look at the topic of this article, using Fluent Bit routing for developers. In case you missed the previous article, check out the top three telemetry pipeline filters where you explore the most useful filters for manipulating and controlling your telemetry data.

This article will be a hands-on exploration of routing patterns that help you as a developer building sophisticated telemetry pipelines. We'll look at how to direct telemetry data to different destinations based on tags, patterns, and conditions in your Fluent Bit configurations.

Cloud Native Rejekts NA 2025 - Expanding Your Toolbox: Beginners Guide to Controlling Kubernetes Logs (slides)

Today I spoke at the always fun event taking place before KubeCon + CloudNativeCon NA, Cloud Native Rejekts. 

Since my transfer from the application development domains to the cloud native observability domain more than three years ago, I've never missed a single CFP for this event. This year it was in another amazing location, The Academy of Medicine in Atlanta, GA.

In the past I've shared observability topics in a session on Perses,  a session providing OpenTelemetry insights, and a session on integrating Fluent Bit with OpenTelemetry including a live demo. Today I told a cloud native story helping developers gain control of their logs in Kubernetes environments while within their inner development loop.

 Below you will find the session slides, abstract, and location details for this Atlanta based event.

Mastering Fluent Bit: Controlling Logs with Fluent Bit on Kubernetes (updated)

This is a special update to the original Controlling Logs with  Fluent Bit on Kubernetes article published previously that is no longer valid.

The issue requiring this update arose over last weekend when I discovered that Broadcom, who acquired VMWare, who were the custodians of the bitnami catalog, did something not so nice to all of us.

In this issue, they announced that the catalog would be moved in August 2025 to a legacy catalog in favor of a 'secure' catalog and no longer updated.  

This meant that the current Logs Control Easy Install project, the workshop Controlling Logs with Fluent Bit on Kubernetes, and the original article had to all be updated.  I spent this last weekend and most of this week bringing all three of these artifacts up to date with a new application workload to replace the use of Ghost CMS.

Let's take a look at what these changes meant to the original article and provide you with a new guide, using Fluent Bit to get control of logs on a Kubernetes cluster.
